Specification of Letters Patent.

Patented Dec. 2%, 1918.

Application filed February 23, 1918. Serial No. 218,843.

To all whom it may concern Be it known that I, HIRAM O. MILLER, a citizen of the United States, residing at Parkesburg, in the county of Chester and State of Pennsylvania, have invented certain new and useful Improvements in Ash- Sifters, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain improvements in ash sifters and it is an object of the invention to provide a device of this general character including novel and improved means whereby the same is rendered sub stantially dust proof.

It is also an object of the invention to provide a novel and improved device of this general character including an inclosing receptacle in which a screening element is mounted for vibration and wherein means are employed operable exterior of the receptacle for vibrating the screening element.

Another object of the invention is to provide a novel and improved ash sifter including a screening element provided with a discharge for the coarser particles together with means for controlling the discharge of the coarser particles from the screening element.

A still further object of the invention is to provide a novel and improved device of this general character provided with two compartments above which a screening element is mounted for vibration and so positioned relative to the compartments whereby one of the compartments receives the siftings from the screening element while the second compartment receives the coarser particles, such as cinders or the like which are separated by the screening element from thesiftings.

The invention consists in the details of construction and in the combinationand arrangement of the several parts of my improved ash sifter whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein:

Figure 1 is a vertical sectional view taken through an ash sifter constructed in accordance with an embodiment of my invention;

Fig. 2 is a sectional view taken substantially on the line 2-2 of Fig. 1; and

Fig. 3 is a sectional view taken substantially on the line 33 of Fig. 1.

As disclosed in the accompanying drawings-R denotes a receptacle of predetermined configuration and dimensions and which has its upper end open and the interior of said receptacle is divided into the compartments A and B by the transversely disposed partition P. The upper end portion of the partition P is inclined so that the top of the compartment A is restricted.

The upper portion or top of the compartment- B afl'ords communication with a funnel like member F depending within the compartment B so that the particles delivered within the member A may be discharged into the bucket or the like positioned within the compartment A. A side wall of the receptacle R is provided with the door D in communication with the compartment A that a bucket or other container may be readily applied to or removed from within the compartment A or whereby the particles delivered within the compartment may be readily removed by a shovel or other implement in the event a container is not employed.

The compartment B is adapted to receive the siftings or fine particles passing through the screening element E to be hereinafter more particularly referred to and in order that such siftings or the like may be readily removed from the compartment B I provide an end of the receptacle R with a door affording communication within the receptacle R.

Seating upon the upper edges of the receptacle R is a casing or frame C and which is provided along the opposed faces of its side members 1 with the guide or track ways 2 upon which are adapted to rest the outwardly directed bearings 3 carried by the side walls 4 of the screening element E, connected at one end by the wall 4. The lower portions of thewalls 4 and 5 support a perforate fabric 6 preferably of wire mesh of predetermined gage. The walls 4 are provided below the fabric 6 with the guide ways 7 to afford means whereby an imperforate slide S may be disposed beneath the fabric 6 to prevent the dropping of siftings or other fine particles from the element E when the occasions of practice may so require.

The end of the element E remote from the wall 5 constitutes a discharge for the coarser particles separated by the fabric 6 and said open or discharge end of the screening element E is under control of the gate G to be hereinafter more particularly referred to.

Extending outwardly from the end wall 5 adjacent the top thereof and at substantially the longitudinal center of said wall is a single bar 8 terminating in a downwardly facing hook which is adapted to be detachably engaged with the crank 9 of the shaft 10.

The shaft 10 is interposed between the side members 1 of the casing C and is r0- tatably supported thereby, and the end portion of said shaft extends exteriorly of the casing or frame C and is provided with the upstanding lever or handle 11 whereby rocking movement may be readily imparted to the shaft 10. When the shaft 10 is rocked it will be at once self-evident that the element E is reciprocated and at the same time is given a slight swinging movement in a vertical plane. This compound movement of the screening element assures an effective separation of the ashes placed in the element.

The screening element E is of such a length and so positioned within the frame or casing C as to cause the coarser particles such as cinders or the like separated from the ashes to be discharged within the funnel F when the discharge end of the element E is open. Should it be desired to retain the separated particles or cinders within the element E the gate G is moved into closed position. After the screening operation has been completed, the element E may be readily removed from within the frame or casing C to any desired point. This removal of the element E also permits the same to be carried to a stove or the like so that the ashes to be sifted or separated may be placed therein without the necessity of hauling the ashes to-the sifter proper. By the elimination of this hauling, it will be at once understood that a further means is provided for eliminating undue dust within a room. The upper portion of the screening element has coacting therewith a re-- 'movable lid or cover. Lwhereby the escape of dust is further assured and it is also preferred that this cover or lid L be maintained in applied position during the vibration of the element E. It is also desired that the top or upper face of the casing or frame C be closed by a removable cover or lid L.

The gate G is disposed transversely of the screening element E adjacent the discharge end thereof and the upper longitudinal marginal portion thereof is provided with the trunnions l2 rotatably engaged with theside walls 4 and coacting with said trunnions are the winged nuts 14 whereby the gate Gr may be effectively locked in closed position or at any desired angle of inclination. By holding the gate G at various angles the dis charge of the cinders or other separated material may be controlled or retarded as the occasions of practice may determine. It is also to be noted that the gate G is positioned inwardlv of the discharge end of the ele ment E so that the cinders or other separated material after passing beneath the gate G may have further separated therefrom any minute particles which may pass therewith below the gate. 7

It is also preferred that the screening element E be disposed on a slight inclination toward its discharge end so that the discharge of the coarser particles such as cinders or the like along the screening element is materially facilitated, during the vibra tion of such element E.

From the foregoing description, it is thought to be obvious that an ash sifter constructed in accordance with m invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated and it wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as herein claimed. 7
